Sharath's DVD is of Primary series so it doesn't cover Dwi pada sirsasana (2nd series asana) but it does include the dwi pada entry to sputa Kurmasana.
Unfortunately it's not that much different than my own, what does he do different for the 2nd series version where you stay in the posture for five breaths, is there different placement or did he just get better at it?
The DVD is excellent by the way, beautifully produced. Back when I first started Ashtanga and for quite some time, I was doing the shorter, forty minute David Swenson version of the practice offered in the back of his Ashtanga book and on his video 'Ashtanga Short forms'. Sharath's DVD goes at quite a pace, the whole practice in just over an hour and yet it never seems rushed. I practiced along with this video for a long time, it allowed me to practice the full series before rushing off to work.
Later I just got up earlier and would slow the practice down as much as possible, back then though when I thought I only had an hour to practice, Sharath's DVD was a godsend.
Here's another preview, this time of Utkatasana to Virabhadrasana showing the exits Sharath was encouraging us to use in conference recently.
